Let the difference between consecutive terms be D. If the middle term is 30, then the term before it is 30-D, and the term after it is 30+D. So the sum of these three terms would be (30-D) + 30 + (30+D) = 3*30.
Extending this sum to include all 11 terms centered around 30, we see that any addition of D is canceled by a balanced subtraction, leaving you with 11 copies of 30. So the value of the sum is 11*30 = 330.
The heat of the sun penetrates the atmosphere and warms the Earth's surface. The warmed rEarth Radiates and this heat back into the atmosphere.The gases the surround the atmosphere such as carbon dioxide , methane , nitrous oxide and water vapour absorb some of the radiated heat and send it back to the Earth . This<em> trapping of heat from the Sun by excess carbon dioxide and other gases present in the atmosphere</em> is known as the <u>greenhouse effect</u>. The gases involved in the phenomenon are called <u>greenhouse gases.</u>

Answer:
25 more inches
Step-by-step explanation:
Answer:
The measure of angle x is 122.5 degrees.
The measure of angle y is 57.5 degrees
Step-by-step explanation:
180=y+x
y=x-65
180= (x-65)+x
180=2x-65
245=2x
x=122.5
y=122.5-65= 57.5
